The functional versatility and flexibility of multifunctional metasurfaces are significant for various applications. This study proposes an active programmable coding metasurface that integrates transmission and reflection control of polarized electromagnetic waves in real time.
The functional versatility and flexibility of multifunctional metasurfaces are of great significance for the application of electromagnetic (EM) metasurfaces in military stealth, holographic imaging, base station antennas, and other fields. Nevertheless, the functions of active programmable coding multifunctional metasurfaces are mostly reflective or transmissive, and the research on active multifunctional metasurfaces with transmission and reflection integration is still in its infancy. Here, a transmission reflection integrated active programmable coding metasurface is proposed to manipulate the transmission and reflection of different polarized electromagnetic waves independently in real time. As a proof of concept, a metasurface that can implement diverse programmable functionalities is designed. Numerical and experimental results indicate that the strategy has excellent performance in beam control and polarization conversion, which provides tremendous potential for extending highly integrated multifunctional devices.
